Lack of sleep can hurt your health, as well as your ability to lead your team effectively, reports Inc. Eti Ben Simon, a neuroscientist and postdoctoral fellow at UC Berkeley's Center for Human Sleep Science, points to several studies that track sleep's impact on productivity, including one by Christopher M. Barnes and Nathaniel F. Watson published in February 2019 that looked at how sleep can help maximize employee effectiveness. Team leaders' lack of sleep could even diminish their perceived charisma in the eyes of their employees, according to another study by Barnes, along with Cristiano L. Guarana, Shazia Nauman, and Dejun Tony Kong, published in May 2016. "A good night's sleep is important for every system in our bodies from our brains to how we're motivated, to how we deal with stress, all the way down to our immune response--which is very relevant right now," says Ben Simon. Sleep "is tied to optimal functioning," says Aric Prather, an associate professor at UCSF Weill Institute for Neurosciences, who has studied the subject for 15 years. Sleep plays a role in emotional health and physical health and is critical for a strong immune system, he says. Get the full story at Inc.com.
